11 Plenary Lecture 1 Numerical Simulation of Non-linear Dynamics of Vibration Transport Machines with Independently Rotating Vibration Exciters Professor Sergey A. Rumyantsev The Department of Mechanics of Solids Ural State University of Railway Transport Ekaterinburg, Russia srumyantsev@math.usurt.ru Abstract: Vibration transport machines (VTM) are intended for transporting and/or separating variable bulk materials. Most of these machines are constructed as solid bodies (working elements, WE) fixed on springs or by means of other elastic elements that enable their plane-parallel motion. The motion of working elements is excited by special devices called vibration exciters (VE). VE act as unbalanced rotors driven by electric motors. Most of researchers only explored synchronous motions of VE. We had stated the problem of transient dynamic processes researching. These processes are accompanying the start of the machine from its stand still until its reaching (or not reaching) stabled synchronous motion. This approach allows evaluating the time until synchronization and the type of connections between this time and various factors. The research was carried out using the mathematical model of dynamics of vibration transport machines with random quantity of independently rotating vibration exciters. This mathematical model is based on numerical solution of differential equations system that describes the VTM dynamics as dynamics of Vibration Transport Machine Driven Electric Motors electromechanical system in case of asynchronous motors with random quantity of poles pairs. This mathematical model allows describing not only the influence of motors on non-stationary VTM dynamics, but also the influence of VTM dynamics on electromagnetic processes in the motor. It also makes it possible to calculate currents of the real three-phase motor. The results of numerical simulation of one- and two-mass machines dynamics in cases of two, three, and four vibration exciters mounted on the lower mass of the VTM are represented in graphic form. We were interested in creating a two-mass machine, both masses of which are oscillating insignificantly while it is not loaded with bulk materials, but after loading it comes to a resonance and its vibration amplitude increases. We have found such parameters by which the abovementioned dynamics type appears. With the using of resonance it is possible to confine with moderate vibration amplitude of the lower mass which would lead to substantial electrical energy savings at the expense of decreasing drive motors capacity.

12 Plenary Lecture 2 Response of High Speed EDS Maglev Train Moving on a Suspended Guideway Shaken by Horizontal Earthquake Professor J. D. Yau Department of Architecture Tamkang University TAIWAN jdyau@mail.tku.edu.tw Abstract: This paper presented a computational framework of interaction analysis for an EDS (electro-dynamic suspension) maglev train traveling over a suspension bridge shaken by horizontal earthquakes. The suspended guideway girder is modeled as a single-span suspended beam and the maglev train traveling over it as a series of maglev masses. To tune the magnetic forces in a maglev suspension system, an on-board hybrid LQR+PID controller is designed to control the dynamic response of a running maglev mass. Then the governing equations of motion for the suspended beam associated with all the controlled maglev masses are transformed into a set of generalized equations by Galerkin s method, and solved using an incremental-iterative procedure. Numerical investigations demonstrate that when a controlled maglev train travels over a suspended guideway shaken by horizontal earthquakes, the proposed hybrid controller has ability to reduce the vehicle s acceleration response for ride quality.

13 Plenary Lecture 3 Planning the Shrinking Cities: New Approaches for the Twenty-First Century Professor Francesco Rotondo Department of Civil Engineering and Architecture Polytechnic University of Bari Italy f.rotondo@poliba.it Abstract: Shrinkage has increasingly become a standard pathway of urban and regional development in many European cities and regions. Shrinking is generally seen in the literature as a negative phenomenon: certain strategies may, however, trigger off positive effects, such as social networking opportunities, affordable housing, and increased sense of identity and opportunity change. Focusing on the effects of urban development should be seen as a priority, attempting to seize opportunities for the integration of a range of urban policies, making the most of scarce resources. Facing the shrinkage it means changing our common approaches to urban planning, abandoning the growth paradigm in search of methods capable of generating a positive De-Growth, as Serge Latouche has defined it. Density, Quality, Greening, Sustainability, Participation, are the key words of such approach, to develop in the shrinking cities. Brief Biography of the Speaker: Francesco Rotondo graduated with a M.S. degree in Civil Engineer from the Polytechnic University of Bari, Italy in From 2000 to 2003 He studied in the University of Pisa, Italy, and graduated in 2003 with a Ph.D. degree in Urban Planning (Sciences and Methods for the European cities and territories).

14 Plenary Lecture 4 Sustainable Mobility in Mid-Sized Cities Assistant Professor Paulo Ribeiro Universidade do Minho Departamento de Engenharia Civil Escola de Engenharia II Campus de Gualtar Braga Portugal pauloribeiro@civil.uminho.pt Abstract: Mobility has an important impact on the overall functioning of cities and quality of life of citizens. On the other hand, motorized road traffic is associated with high levels of noise and air pollutant emissions along with congestion and other externalities, leading to considerable social and environmental costs and degradation of human health, causing less healthy and consequently less sustainable urban environments. Therefore, more sustainable transport modes such as walking and cycling are envisaged, as well as the improvement of the public transport performance. Conventionally, mid-sized cities in Portugal, as well as in other European countries, are characterized by higher densities of population and households in relation to its surroundings, mainly at the municipality level. On the other hand, the city itself is concentrated in a small urban agglomerate where most health, educational, financial and administrative facilities are located, resulting in major traffic generators and central active points of a regional coverage. Land use and mobility planning represents a key issue to achieve a more sustainable urban transportation system. For that, sustainable mobility plans can be considered the first tool towards action. These plans can be formally divided in three phases: the diagnosis of the current situation, the definition of the objectives and concept of intervention in terms of mobility, and the development of proposals for intervention. The diagnosis of the current situation can be made through the supply/demand analysis of the urban mobility system, as well as with the identification of the major mobility constraints for different modes of transport inherent to the functioning of the various subsystems of the overall transport system. In order to integrate the sustainability principles in mobility proposals, it is necessary to characterize and define the main objectives of future interventions as well as the level of priority. In this stage, the introduction of the strategic vision of the authorities responsible for the management of the city transportation system represents an important input for planning as well as its underlying commitment with the selected solutions. In order to describe the planning process framework, several proposals will be presented for four different types of urban agglomerates of mid-sized cities in Northern Portugal, namely Viana do Castelo, Barcelos, Póvoa de Lanhoso and Arcos de Valdevez. Several priority actions were identified and detailed proposals were developed for these areas that included the reorganization of land use in the central area of some cities, thus supporting walking and cycling, and represents an innovative concept of urban transformation of historical and cultural areas of interest to promote economic vitality of those areas, the integration of a multimodal approach in larger cities, the development of air quality monitoring systems, among other solutions to promote the sustainability of these cities.
